BOB-

SLED.

SPEGIFICATION forming part of Letters Patent No. 613,889, dated November 8, 1898.

Application filed March 29, 1 898.

To all whom it may concern:

Be it known that I, WILLIAM G. SCOTT, a citizen of the United States, residing at Rock Dell, in the county of Olmsted and State of Minnesota, have invented certain new and useful Improvements in Bob-Sleds, of which the following is a specification.

The object of this invention is to construct a bob-sled in which the bolsters are suspended from suitable supports connected to the runners in order that the runners may oscillate without changing the position of the bolsters; and it consists in details of construction pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a bob-sled embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse section through the front bolster. Fig. 4 is a transverse section through the rear bolster. Fig. 5 is a lengthwise section of a portion of the reach at the point of connection of the rear bob. Fig. 6 is an isometrical representation of the wearing-plate forming a support for the rear bolster.

The bobs consist of runners, each composed of a center section 1, of wood, to which are riveted side plates 2, and to the under face of the center section is bolted the shoe 3. To the upper face of each runner is secured a knee 4, having the upper center section in semicircular form, forming a recess. The beam is composed of the two parallel bars 5, extending transversely of the bob and riveted together, between which are riveted loops 6, surrounding and located in the semicircular-formed recesses of the knees, thereby suspending the beam from the knees in a manner to permit the oscillation of the runners without changing the position of the beam. Brace-bars 7, bent in the form of the knees, to which they are secured at their free ends, have their center portion bent in semicircular form and receive loops 8, secured between the bars of the beam. These beams hold the runners at right angles to the beam,but permit of their oscillation. The forward ends of the side plates of the front bob support eyes 9, to which are linked the braces 10, to which the tongue 11 is secured.

Between the bars 5 of the beam of the front bob is secured a king-bolt 12; also, strips 13 Serial No. 675,648. (No model.)

Around the king-bolt is located a wearing plate 14, held in place by bolts 15, extending between the plates of the beam. A bolster 16 has a central opening receiving the kingbolt, and a wearing-plate 17 is secured to the under face of the bolster by the bolts 18. These wearing-plates lie in contact.

To the rear face of the bolster 16 is secured a reach 19, held in proper position by the braces 20. A greater portion of the reach has rounded edges, and an opening 21 is formed through the reach near its connection with thefront bolster.

Between the bars of the beam of the rear bob are secured two angle-bars, composed of the shank portion 22 and the horizontal portion 23, and beneath the horizontal portions are located wearing-blocks having a shank portion 24 and headed end 25, as shown at Fig. 6.

A connection is formed between the rear bob and reach through the medium of a yoke composed of the side bars 26, joined to a collar 27, and to their free ends are secured loops 28, forming a rectangular space 29, receiving the horizontal portion 23 of the angle-bars. The under face of this end of the yoke rests upon the wearing-blocks. To the upper surface of the loops 28 is secured the rear bolster 30 by bolts 31, passing through the parts, thus holding the free ends of the bars of the yoke properly separated.

The reach extends through a loop 32, secured to the face of the rear bolster. Between the front end of the side bars 2 of the runners of the rear bob are pivotally secured draw-rods 33, their forward free ends connected to the bars of the yoke by means of theloops 34 in order that the parts may be loosely connected and have. a freedom of movement.

The collar 27 has a connection with the reach through the medium of a latch com posed of the two sections 35 and 36, pivotally connected. The section 35 has an upturned portion 37, adapted to enter the opening 21 Ioo disengaged. The collar is moved along the l to the reach, the ends of the yoke made in reach until the projection 37 of the section 35 passes up through the opening 21 in the reach, when a pin 39 is passed through the portion, thereby holding the collar in position on the reach.

By this construction of bob-sled the runners have an oscillatory movement in their connection with the bolsters and the braces are above the lower surface of the beams, thereby presenting an unobstructed space between the beams, and by forming a sliding engagement between the rear bolster and rear bob permits the rear bob to Work forward and backward under the load in moving over uneven roads. The bolsters being suspended from the beams permit of the 0s cillation of the runners without changing the position of the beams, and the connection between the bobs being through the collar and reach they are independent in their oscillations in vertical as well as horizontal planes.

Itwill be noticed that the ends of the knees are turned down and are located between the side plates 2 of the runner, which serves to hold the knees in an upright position.

I claim as my invention 1. In a bob-sled, the combination of two bobs each supporting a bolster, a reach having a pivotal connection with the front bob and guided by the rear bob, a yoke connected loop form and having a sliding connection with the beam of the rear bob.

2. In a bob-sled, the combination of two bobs, a reach connected to one bob, a yoke connecting the other bob and reach, and a connection between the yoke and reach consisting of a collar connected to the yoke and surrounding the reach, and a pivoted latch connecting the collar and reach.

3. In a bob -sled, the combination of two bobs, the runners of each bob supporting a knee having a recess in their upper faces, a beam composed of two parallel bars, and loops supported by the bars and located .in the recess of the knees.

4. In a bob-sled, the combination of two bobs, the runners of each supportinga knee, a beam composed of two parallel bars, a connection between the beam and knees, a kingbolt supported by one of the beams and a bolster adapted to turn on the king-bolt.

5. In a bob-sled, the runners of which are composed of a center wooden portion, two metallic side plates secu red to the center portion, and a shoe secured to the under face of the center portion and side plates.
